Takeaways: Red Sox 4, Mets 3

FORT MYERS, Fla. -- Takeaways from the Fort, where the Boston Red Sox beat the New York Mets, 4-3, scoring the winning run in the bottom of the ninth on a passed ball.

• It was another big day at the plate for Mookie Betts, who hit a top-of-the-wall double off Mets ace Matt Harvey, then followed that with a triple off top Mets prospect Noah Syndergaard, scoring on a wild pitch. He’s now batting .435 (10-for-23) in seven spring games.

“We had a chance to watch four innings of one of the better pitchers in the game,’’ Red Sox manager John Farrell said of Harvey, who did not allow a run while allowing four hits, no walks and striking out three. “Any time you know a guy has come back from what he’s gone through [Tommy John surgery], to see the power, and the shape of his secondary pitches, he’s a heck of a pitcher.

“Mookie, obviously, impressive with a 3-2 changeup he hits off the wall. He’s put up very good at-bats against very good pitchers and he continues to grow in confidence.''

Harvey threw a similar full-count changeup to strike out Dustin Pedroia to strand Betts after his double.

• It was an even better day at the plate for catcher Matt Spring, who has spent 11 seasons in the minors and is in Sox camp for the first time as a non-roster invitee. Spring homered off Syndergaard and also doubled twice, the last double putting Garin Cecchini in position to score on a passed ball.

“The guy comes into camp, he’s got No. 81 hanging in his locker, he knows his place in the organization, and that’s not to take away anything from how hard he works, but today is certainly a day he’ll remember. And rightfully so,’’ Farrell said.

• Knuckleballer Steven Wright, identified by Farrell before the game as a pitcher who gives the Sox a sense of comfort knowing he would be available if a starter goes down, pitched three scoreless innings.

• Reliever Alexi Ogando gave the Sox a powerful fourth inning, going pop out, whiff, whiff.

“Quality inning of work,’’ Farrell said. “I thought he threw some splits today that had more consistent and greater depth to it. He’s in a good place, with three weeks to go in camp.''

• The Sox are waiting at least a day to see if the right biceps tendinitis that knocked pitcher Joe Kelly out of Monday’s game in the third inning will be something other than a minor trifle.

Kelly seems to think that's the case. The 26-year-old right-hander, who described the tightness in his biceps as getting progressively worse until he could throw nothing but fastballs, claims he endured a similar issue in camp with the Cardinals last spring, and it proved to be a minor glitch.

Plenty of pitchers have not been as fortunate. Kelly’s 2012 call-up to the big leagues by the Cardinals came after they released another pitcher, Scott Linebrink, who was dealing with biceps tendinitis and shoulder inflammation. And Cole Hamels, who has surpassed Nat King Cole, Cole Porter and Old King Cole as the best-known Cole in New England, started last season on the disabled list with biceps tendinitis, though he still managed to throw 204 2/3 innings.

“It’s not uncommon for pitchers to experience some kind of soreness as we’re stretching them out,’’ Farrell said. “I know it’s something Joe has dealt with in the past. It’s a day in which his velocity wasn’t normal. Again, I think some of our starters are going through a little bit of a dead-arm period. I know it affected him most when he tried to throw with a little extra velocity on that last pitch. You could see him have a different action on the mound and it was clearly time to get him out of the game.

“We’ll have a chance to re-evaluate him tomorrow when he comes back and see what treatment he needs going forward and any overall adjustment to his schedule.''

It’s a safe assumption that Kelly won’t make his next start, scheduled for next Sunday here against the Phillies. But if it is minor, as Kelly contends, there is little reason yet to believe that Kelly will not make his first regular-season start, which right now lines up to be April 11 in New York against the Yankees.

Farrell did not rule out the possibility that Kelly will undergo an MRI. “We know it is in the belly of the biceps,’’ he said. “It’s not in any joint of any kind. We’ll get a better read tomorrow.''
