In the midst of a six-game losing streak in a season filled with low points, Cuban outfielder Rusney Castillo is providing plenty of optimism and excitement for Boston Red Sox fans.

The 27-year-old, who reportedly agreed to a seven-year, $72.5 million contract with the Red Sox, arrived at Fenway Park on Saturday morning and made his first rounds with the fans. Castillo signed autographs and chatted with players a couple of hours before first pitch.

While there is no timetable as to when the deal can be made official, manager John Farrell told reporters that he hopes to have Castillo get some at-bats in the minors when that day comes. Farrell also added that he’s excited about the power the free agent can add to the lineup, as he compared the 5-foot-9, 205-pound infielder to “a shorter version of (Yasiel) Puig.”
