Chapman (back) was removed in the eighth inning of Sunday's 4-3 win over the Dodgers due to back tightness, Chris Cotillo of MassLive.com reports.

Chapman took the hill to begin the eighth inning and issued a pair of walks and induced a Shohei Ohtani flyout before being removed from the contest. The 37-year-old was apparently dealing with a tight back, which likely explains why his average four-seam fastball velocity was about four ticks behind his season-long average during the outing. The back issue wasn't something that manager Alex Cora wasn't overly worried about, noting that he expects the closer to avoid a trip to the injured list. That being said, the Red Sox may look to stay away from using Chapman for the next day or two to give him extra time to heal up from the back issue.

Chapman was removed in the eighth inning during his relief appearance in Sunday's game against the Dodgers due to an apparent injury, Chris Cotillo of MassLive.com reports.

After entering the game in the top of the eighth, Chapman walked the first two batters he faced, then induced a Shohei Ohtani flyball for the first out of the inning. The Red Sox sent a trainer out to visit with Chapman following that at-bat, and manager Alex Cora then made the decision to pull the right-hander from the game. Though the nature of Chapman's injury likely won't be clarified until after the contest, he sported a four-seam fastball that averaged just 94.6 miles per hour on the afternoon, about four ticks below his season average.

Sands will serve as the Twins' opening pitcher in Sunday's game against the Nationals.

He'll serve as an opener for the third time this season after lasting no more than two innings in starts July 5 and July 12. It's not clear whether Sands will be followed by a bulk reliever such as Travis Adams, or if the Twins will use a true bullpen day.

The Royals recalled Bowlan from Triple-A Omaha on Sunday.

The right-hander will provide Kansas City with a fresh arm in the bullpen, but he's unlikely to be entrusted with a high-leverage role. Over his previous stints in the majors this season, Bowlan has made 17 appearances and has delivered a 4.94 ERA, 1.35 WHIP and 21:9 K:BB in 23.2 innings.

The Yankees recalled Headrick from Triple-A Scranton/Wilkes-Barre on Sunday.

The left-hander spent most of July on the injured list at Triple-A, but he was reinstated last week and is now getting another look with the Yankees. Headrick has made 11 appearances in the majors this season and has a 4.73 ERA, 1.12 WHIP and 16:3 K:BB across 13.1 innings.

Boyle is listed as the Rays' probable starting pitcher for Tuesday's game against the Yankees in New York.

Boyle will fill the spot in the rotation that opened up when Taj Bradley was optioned to Triple-A Durham on Thursday. Over 15 appearances (14 starts) in the minors this season, Boyle had been one of Triple-A's top hurlers with a 1.73 ERA, 0.97 WHIP and 96:31 K:BB in 73 innings, and he's carried that success over to the majors. In his five appearances (one start) with Tampa Bay, the right-hander has spun a 1.42 ERA and 0.63 WHIP while punching out 18 batters over 19 innings. He made a five-inning appearance as recently as July 6, so he should be capable of working deep enough into Tuesday's start to qualify for a win. Given his sterling ratios, Boyle looks worthy of rostering in just about any fantasy league now that he's in line for an extended stay in the rotation.

Ginn will start Sunday's game against the Astros.

Ginn was called upon to fill the vacant spot in the Athletics rotation Tuesday against the Rangers, and while the right-hander was limited to 58 pitches, he fared well in a no-decision, limiting Texas to one earned run on five hits and one walk while striking out two over five innings. Ginn will be rewarded with a second start, and he should be capable of giving the Athletics around 70-80 pitches Sunday.

Lee allowed four runs on four hits in just an inning of work in Saturday's 6-1 loss to the Blue Jays. He struck out one.

With the Tigers down 2-0 entering the top of the ninth inning, Lee let things get out of hand with one of his worst outings of the season. The rookie righty started his campaign by posting a 2.05 ERA across his first 25 games, but he now has a 15.88 ERA over his last six appearances, getting tagged for multiple runs three times during the stretch. Fatigue is potentially becoming a factor for Lee, and the team could decide to send him back to Triple-A Toledo at some point for a reset.

Latz worked in relief in wins over Atlanta on Friday and Saturday, covering 1.1 innings between his two appearances while allowing one earned run on two hits and three walks.

Prior to his pair of relief appearances, Latz tossed five innings of one-run ball in a start against the Tigers on July 20, but he was never expected to receive multiple turns through the Texas rotation. The 29-year-old lefty has proven to be a dependable spot starter when called upon this season, but the Rangers aren't likely to have a permanent rotation spot available for him unless another starter succumbs to an injury. Even in that scenario, Jon Gray -- who was activated from the 60-day injured list earlier this week and moved to the bullpen -- might be the preferred option over Latz to fill any void in the rotation.

Vest (5-2) allowed two runs on three hits across an inning of relief to take the loss in Saturday's 6-1 defeat to the Blue Jays. He struck out one.

With the game scoreless through seven innings following a dazzling start by Tarik Skubal, Vest let things get away in the eighth. It was the first time the veteran righty had allowed more than one run in an appearance since June 15, and he had posted a stellar 0.96 ERA in nine games since then. Overall, Vest still has a solid 2.58 ERA across 45.1 innings this season to go along with 51 strikeouts, and he should be able to bounce back from the rough outing and get back to closing out games for the Tigers.
