RHP Josh Beckett (4-3, 6.50 ERA) vs. LHP Brian Matusz (6-12, 4.79 ERA)
Beckett has progressively improved in each of his last four starts, culminating in a victory over Seattle six days ago. He allowed three runs in 6 1/3 innings, striking out seven and walking one. The righty was still peeved at giving up three runs in the seventh inning of that one.
Over his last four starts he has struggled to avoid the big inning — in the 10 innings over that span in which opponents have scored, just twice has Beckett limited them to one run.
He is 6-2 with a 3.61 ERA in his career vs. Baltimore.
Matusz, 23, struggled through a large portion of his first full season but has begun to show the form in recent weeks that has the organization very excited for his future.
The lefty is 3-1 with 2.32 ERA in August, during which he has held opponents to a .239 average and has walked just six batters in 31 innings. Matusz threw seven shutout innings in a win at Fenway Park on July 4.
