Red Sox: First baseman Triston Casas suffered a ruptured tendon in his left knee and is out for the remainder of the season, the Red Sox said. The 25-year-old Casas ruptured his patellar tendon running to first on a slow roller up the line and fell awkwardly in the Red Sox’s victory over the Twins on Friday night. After laying on his back in pain — not moving the knee — he was carted off on a stretcher before being taken to a Boston hospital. The team announced Sunday that he had surgery for a left patellar tendon repair at Massachusetts General Hospital. The surgery was performed by Dr. Eric Berkson. “I talked to him last night,” Chief baseball officer Craig Breslow said in a news conference on Saturday discussing the injury outside the Red Sox’s clubhouse. “We exchanged text messages (today). We all care deeply about just his overall wellbeing.” Manager Alex Cora said Casas worked hard during the offseason to play every day after missing a large amount of last year with torn cartilage in his rib cage. “He did an outstanding job in the offseason to put himself in that situation. It didn’t start the way he wanted it to,” Cora said of Casas’ struggles. “He was going to play and play a lot. Now we’ve got to focus on the rehab after the surgery and hopefully get him back stronger than ever and ready to go next year.” Casas batted just .182 with three homers and 11 RBIs, but Breslow said his loss will be felt, especially with the team’s lack of depth at the position. “He certainly struggled through the first month of the season but that didn’t change what we believe his production was capable of being,” Breslow said. “It’s a big loss. In addition to what we think we were going to get on the offensive side, he was kind of like a stabilizing presence on the defensive side of the field — also a big personality and a big part of the clubhouse.” Cora said there are no plans to move Rafael Devers, who was replaced at third by offseason, free-agent acquisition Alex Bregman, and moved to DH. Casas was placed on the IL on Saturday with infielder/outfielder Abraham Toro selected from Triple-A Worcester.

Padres: Stephen Kolek pitched 5 2/3 scoreless innings in his first major league start and combined with four relievers for the Padres’ eighth shutout of the season, a 4-0 victory over the host Pirates for their fifth straight win. Kolek was recalled from Triple-A El Paso before the game. He made 42 relief appearances for the Padres last season as a rookie after being selected from the Mariners in the Rule 5 draft. Kolek, who had a 6.38 ERA in five starts for El Paso this season, allowed four hits, struck out four and walked two. Jeremiah Estrada, Adrian Morejon, Wandy Peralta and Jason Adam followed Kolek. The eight shutouts are the most in the majors. Xander Bogaerts had three RBIs for the Padres, who scored all their runs in the first two innings off Andrew Heaney (2-3), who was pulled with two outs in the fourth. Manny Machado doubled and scored on Bogaerts’ single in the first. In the second, Elias Diaz led off with his third HR of the season and Bogaerts hit a two-run double to make it 4-0. Heaney allowed eight hits and four walks while striking out three. The Pirates have lost four games in a row and seven of their last eight. Machado had three hits and Bogaerts, Diaz and Luis Arraez added two apiece. The Pirates’ Joey Bart, Ke’Bryan Hayes, Matt Gorski and Tommy Pham had two hits each.
