brandon workmanFinal, Mariners 7-3: And that’ll do it.

The Mariners score all seven of their runs in the fourth inning and hand the Red Sox their seventh straight loss.

Seattle will go for a series sweep Sunday at 1:35 p.m. as these teams wrap up their three-game set.

Mid 9th, Mariners 7-3: Burke Badenhop makes quick work of the Mariners in his first inning on the mound, retiring the side in order on three consecutive groundouts.

The Red Sox now are down to their final three outs. They’ll send Kelly Johnson (who replaced the injured David Ortiz), Yoenis Cespedes and Mike Napoli to the plate against Yoervis Medina.

End 8th, Mariners 7-3: David Ross will be watching the rest of this game from the clubhouse.

The catcher was ejected for the first time in his career after arguing with first base umpire Vic Carapazza. Carapazza and Ross did not see eye to eye on what Ross believed was a check swing. Carapazza saw it as strike three, and he sent the veteran for an early shower.

Mookie Betts led off the eighth inning with a double, but Yoervis Medina retired the next three batters to end the frame.

Mid 8th, Mariners 7-3: Junichi Tazawa shuts down the Mariners in the eighth, retiring the side in order.

Tazawa got Chris Denorfia to ground out to third before striking out both Endy Chavez and Chris Taylor.

Yoervis Medina is now on to pitch for Seattle.

End 7th, Mariners 7-3:Daniel Nava reached on a one-out single, but a double play wiped him off the basepaths and closed out the Red Sox’s fourth straight scoreless inning.

Mike Napoli struck out for the second time today to lead off the frame.

After an excellent relief outing by Alex Wilson, Junichi Tazawa will work the eighth inning for the Red Sox.

Mid 7th, Mariners 7-3: It would not be a surprise if the benches empty at some point during this series.

Following the beaning of David Ortiz and the near-beaning of Yoenis Cespedes (not to mention the pitch to the head suffered by Xander Bogaerts last night), Red Sox reliever plunked Robinson Cano in the backside with one out in the seventh.

Warnings were issued, and nothing more has come of it as of yet, but this certainly will be something to keep an eye on throughout the weekend.

Other than the hit-by-pitch, Wilson was perfect, retiring the other three batters he faced. The right-hander has yet to allow a hit in his 3 2/3 innings of work.

End 6th, Mariners 7-3: There was no Yoenis Cespedes magic this time around.

David Ortiz advanced to second on a balk and third on a wild pitch, but Cespedes was unable to drive him in. The left fielder flied out to center for the final out of the inning.

Bottom 6th, Mariners 7-3: Charlie Furbush picks up two quick outs but will not be allowed to finish the sixth inning.

Brock Holt and Dustin Pedroia both went down swinging on pitches outside of the strike zone to start things off, but Furbush then nailed David Ortiz in the wrist/forearm area with a high fastball. John Farrell and the team trainer came out to check on Ortiz but he appears to be OK.

Furbush was lifted after the hit-by-pitch. Danny Farquhar will come in to face Yoenis Cespedes.

Mid 6th, Mariners 7-3: Alex Wilson strikes out the side and now has retired all eight batters he’s faced.

Chris Taylor, Jesus Sucre and Austin Jackson all went down by way of the K in the sixth.

The Mariners will turn to their second reliever of the day, Charlie Furbush, to work the home half of the frame.

End 5th, Mariners 7-3: As bad as the starting pitchers were today, the bullpens have been lights-out.

Mariners reliever Tom Wilhelmsen handed out a one-out walk to Will Middlebrooks but was otherwise perfect in the fifth, retiring the side with two strikeouts.

Neither Wilhelmsen nor Red Sox reliever Alex Wilson have allowed a hit yet.

Mid 5th, Mariners 7-3: Alex Wilson has no problem completing his first full inning of relief.

Kyle Seager flied out to Daniel Nava in right field, Chris Denorfia grounded out to short and Endy Chavez flied out to Mookie Betts in center to put a quick end to the top of the fifth.

End 4th, Mariners 7-3: Tom Wilhelmsen blows a 97-mph fastball past Mike Napoli, and the Red Sox leave ’em loaded for the second time today.

Bottom 4th, Mariners 7-3: That’ll do it for Chris Young, who gets the hook with the bases loaded and two outs in the fourth.

Dustin Pedroia reached base on a single after David Ross and Brock Holt began the inning with consecutive strikeouts, and Young followed Pedroia’s base hit by walking both David Ortiz and Yoenis Cespedes.

Right-hander Tom Wilhelmsen will be tasked with getting Seattle out of this jam.

Mid 4th, Mariners 7-3: Alex Wilson was able to stop the bleeding, getting Robinson Cano and Kendrys Morales to ground out to end the inning.

That was a rough showing for Brandon Workman, though, who dug his team into a four-run hole before being yanked.

Top 4th, Mariners 7-3: Well, this game went downhill in a hurry.

Brandon Workman, who entered the fourth inning with a 3-0 lead, proceeded to allow hits to seven of the eight batters he faced in the frame. The Mariners used those hits to plate seven runs, capping it off with a three-run home run by Dustin Ackley that just barely cleared the wall to the left of Pesky’s Pole.

Workman picked up just one out in the inning, a strikeout of Endy Chavez.

Alex Wilson now comes on to pitch for the Red Sox.

End 3rd, Red Sox 3-0: Yoenis Cespedes has been the star of this game thus far.

The left fielder, who nailed Kyle Seager at the plate to end the second inning, extended the Red Sox’s lead in the third. Cespedes doubled to the wall in center field, chugged his way to third when Austin Jackson misplayed the ball and scored on a sacrifice fly by Mike Napoli.

Cespedes also drove in Boston’s first run with a sac fly of his own back in the first.

Will Middlebrooks reached on a single later in the third inning, but groundouts by Daniel Nava and Mookie Betts prevented the Red Sox from tacking on any more runs.

Mid 3rd, Red Sox 2-0: Brandon Workman finally enjoys an easy inning, retiring the Mariners in order in the third.

Leadoff man Austin Jackson grounded out to third base, Dustin Ackley lined out to left and Robinson Cano grounded to second.

End 2nd, Red Sox 2-0: The Red Sox are taking it to Mariners starter Chris Young.

The Red Sox put three more men on base against Young in the second inning and pushed across their second run of the game.

The right-hander walked Mookie Betts to open the frame. Betts then stole second and came around to score on David Ross’ double down the left field line.

Young caught a big break, though, when Brock Holt lined into a 4-6 double play, and after after an error allowed Dustin Pedroia to stretch a two-out single into a double, David Ortiz popped out for the second time today to end the inning.

Mid 2nd, Red Sox 1-0: A lesson to visiting teams: Do not — I mean, do not — try to run on Yoenis Cespedes.

Kyle Seager tested the arm of the Red Sox left fielder, and he paid the price. Cespedes gunned him down at the plate with plenty of time to spare for the final out of the second inning.

Seager opened the second with a single, the first of three Mariners base hits in the frame. Seattle was unable to push a run across against Brandon Workman, though, who has bent quite a bit so far today but has yet to break.

End 1st, Red Sox 1-0: We have some early offense here at the ballpark

Brock Holt led off the inning with a base hit, and Dustin Pedroia sent him to third with a double just inside the left field line. Had the ball reached the wall, it might have been enough to score Holt from first, but a young fan spoiled that chance by reaching over and snatching it up.

Holt was forced to stop at third, but he didn’t stay there for long. After David Ortiz popped out to Robinson Cano in shallow right field, Yoenis Cespedes drove the utility man in with a sacrifice fly to the warning track.

Mariners starter Chris Young walked Mike Napoli on four pitches to put runners on first and second, then loaded ’em up by missing high on a 3-2 fastball to Daniel Nava.

The Red Sox couldn’t capitalize, though, as Will Middlebrooks popped out to the pitcher to end the inning.

Mid 1st, 0-0: The Mariners are making Brandon Workman work.

Leadoff man Austin Jackson saw six pitches before grounding out to Brock Holt at shortstop. Dustin Ackley followed with a tremendous at-bat, fouling off seven pitches before drawing a walk on his 12th.

Ackley stole second base after Robinson Cano struck out swinging, but Kendrys Morales grounded out to second to end the inning.

That’s a 25-pitch frame for Workman, though.

The Red Sox now will take their first hacks, with Holt, Dustin Pedroia and David Ortiz due up first against Seattle starter Chris Young.

1:36 p.m.: Aaaand they’re off.

Austin Jackson takes ball one one from Brandon Workman to get things started here on a beautiful afternoon in Boston.

The Mariners will send Jackson, Dustin Ackley and Robinson Cano to the plate first against the tall Texan.

1:10 p.m.: Manager John Farrell gave an update on the two players who left Friday night’s game with injuries: Joe Kelly and Xander Bogaerts.

Kelly is feeling “no ill effects” from the shoulder injury that forced him from the game in the fifth inning, Farrell said, and is expected to make his next scheduled start.

Bogaerts, meanwhile, was held out of today’s starting lineup as he undergoes concussion testing. The shortstop was drilled in the head by a Felix Hernandez pitch and left the game one inning later.

We’ll be getting started here from Fenway in just about 25 minutes.

12:40 p.m.: Red Sox fans got a glimpse this afternoon of Cuban outfielder Rusney Castillo, who made his first appearance at Fenway Park after reportedly agreeing to terms Friday on a seven-year, $72.5 million contract with the Red Sox.

11:45 a.m. ET: What looked to be a sure win for the Boston Red Sox turned ugly in a hurry Friday night.

Typically lights-out closer Koji Uehara was anything but, surrendering five runs with two outs in the ninth inning as the Seattle Mariners came from behind to hand the Red Sox their sixth straight loss.

The Sox won’t have much time to dwell on the defeat, however. They host the Mariners again in a Saturday matinee, their first of two afternoon tilts this weekend.

Brandon Workman will get the nod for the home team as he attempts to snap a losing streak of his own. Workman has taken the loss in each of his last seven appearances (six starts), with his most recent victory coming way back on June 10. The 26-year-old right-hander was solid in his last outing, though, allowing two runs on six hits over seven innings against the Los Angeles Angels on Monday.

Opposing Workman will be veteran righty Chris Young, who has pitched well in his first season with the Mariners. Young carries a 3.07 ERA and an 12-6 record into the weekend and has been the winner in each of his last three starts.

Here are the lineups these pitchers will be facing:

We’ll have plenty more from Fenway Park leading up to first pitch, which is scheduled for 1:35 p.m.
