Shane Prusak was wide-eyed as some of his favorite Red Sox players paraded around in foul ground greeting fans at Fenway Park before Saturday’s game against the Astros

The Yankees may finally have an explanation for Luis Severino’s sophomore slump. Forced to leave his start in the third inning on Friday, the hurler has been diagnosed with a mild strain of his right triceps, which will necessitate a stint on the 15-day disabled list.

Chris Sale became the fourth White Sox starter in franchise history to win each of his first eight starts in a season, joining Eddie Cicotte (12, 1919), John Whitehead (eight, 1935) and Jon Garland (eight, 2005) with Friday’s complete-game effort in a 7-1 win against the Yankees.

Michael Brantley knows he is too valuable to the Indians to push through any lingering issues with his surgically-repaired right shoulder and risk a setback. The left fielder alerted the team that he was not bouncing back well after games. Prior to their game against the Twins on Saturday, the Indians placed Brantley on the 15-day disabled list due to inflammation in his shoulder, which was operated on in November.

Top Astros prospect Alex Bregman said Saturday he felt “very comfortable” after playing his first game at third base as a professional in the first game of a doubleheader Friday for Double-A Corpus Christi. Bregman was selected No. 2 overall in last year’s Draft out of LSU as a shortstop and played short until getting the start at third on Friday.

Yankees right-hander Luis Severino exited in the third inning of his start Friday night, and he was placed on the 15-day disabled list Saturday with a mild strain in his right triceps.

Catcher Miguel Montero was activated from the disabled list Saturday, and he was in the Cubs’ starting lineup.

For most, pitching is a constant game of tweaks in order to find a groove. Pirates left-hander Tony Watson said he hasn’t made a major mechanical change.

Astros manager A.J. Hinch showed his growing trust in reliever Ken Giles by bringing him into the seventh inning of a tight game Friday.

White Sox right fielder Adam Eaton entered Saturday afternoon’s contest at Yankee Stadium ranked second in the Majors with a 2.8 bWAR, trailing the Astros’ Jose Altuve (2.9).

Nationals right-hander Matt Belisle, who is on the disabled list because of a right calf strain, threw a bullpen session for the first time on Saturday. Belisle said he feels great but the next steps are up to the team.

Maybe they weren’t on our radars on Opening Day, but what does that matter now? One of the coolest things about every All-Star Game is watching the players who are there for the first time.

C. J. Cron homered in the eighth and then dropped in a two-run go-ahead single in the ninth as the Angels snapped a six-game losing streak with a 7-6 victory over the Mariners in Friday night’s series opener at Safeco Field.

Rockies right-handed rookie Jon Gray struck out eight in seven innings to earn his first Major League win, 5-2, over the Mets at Coors Field on Friday night.

Rockies shortstop Jose Reyes was suspended without pay through May 31 for violating Major League Baseball’s Joint Domestic Violence Policy. In total, his suspension will span a total of 52 regular-season games.

Cardinals center fielder Randal Grichuk, who was miffed that he narrowly missed robbing Albert Pujols of a home run on Thursday night, got a chance at redemption in Friday night’s series opener vs. the Dodgers and he didn’t miss, going over the wall to take a long ball away from Howie Kendrick.
