The Red Sox recalled Rivera from Triple-A Worcester on Saturday.

After turning in a 3.08 ERA and 1.21 WHIP across 38 innings in Triple-A, Rivera will be making his first career start in the majors Saturday, per Ian Browne of MLB.com. It's worth noting that Rivera threw just 29 pitches during his last Triple-A outing and will be working on three days' rest, so he isn't likely to pitch very deep into Saturday's contest. Brett Harris was sent down to Worcester in a corresponding move.

The Twins claimed Anderson off waivers from the Red Sox on Saturday and optioned him to Triple-A St. Paul.

Boston designated Anderson for assignment Monday, but he'll end up back on a new organization's 40-man roster after being picked up by Minnesota. The 26-year-old righty has given up three runs in eight major-league innings this season but owns a 4.81 ERA and 1.38 WHIP over 58 frames in the minors.

Caballero isn't in the lineup for Saturday's game against Washington.

Caballero will catch a breather Saturday after tallying four hits in his last three games while collecting an RBI and a pair of steals. While Caballero rests, Anthony Volpe will pick up a start at shortstop and bat eighth.

Kreidler isn't in the lineup for Saturday's game against the Angels.

After going 2-for-24 (.083) with nine strikeouts to begin the month of July, Kreidler will retreat to the bench for a third consecutive game while Tristan Gray starts at shortstop and bats eighth.

Jeffers isn't in the lineup for Saturday's game against the Angels.

After going 1-for-4 with a double and a walk during his return from the injured list Friday, Jeffers will take a seat Saturday as he eases his way back into major-league action. Victor Caratini will start behind the plate and bat sixth.

Peraza isn't in the lineup for Saturday's game against the Twins, Jeff Fletcher of The Orange County Register reports.

Peraza will grab a seat on the bench after going 1-for-4 with two strikeouts during Friday's series opener. Vaughn Grissom will take over at the keystone and bat fifth.

Matthews (4-6) took the loss Friday against the Angels, giving up four earned runs on nine hits and two walks while striking out three batters over six innings.

Matthews had given up just one hit and one walk through the first three innings of Friday's contest, but things began to fall apart after he conceded a solo homer to Vaughn Grissom to lead off the fourth. Jorge Soler doubled during the ensuing at-bat and later scored on a balk, and the Angels began the fifth inning by putting up four consecutive hits against Matthews, adding two more runs to their lead. The 26-year-old righty has now coughed up eight earned runs in 10.2 innings across his last two starts, and he'll take a 4.57 ERA, 1.22 WHIP and 54:18 K:BB through 67 innings into the All-Star break.

Yates gave up one hit in a scoreless ninth inning to earn the save in Friday's 4-3 win over the Twins.

Yates has continued to show improvement on the mound recently, allowing just two runs (one earned) while striking out 15 batters across his last 10.2 innings. He's now recorded two of his team's last three saves.

Rodriguez (3-2) earned the win over the Twins on Friday, allowing three earned runs on six hits and a walk across 5.1 innings. He did not record a strikeout.

Rodriguez began the game by allowing a leadoff double to Trevor Larnach, who eventually came around to score and give Minnesota an early lead. Rodriguez responded by firing four consecutive scoreless frames while the Angels' offense churned out four runs, but he was pulled after allowing three consecutive hits and two runs in the sixth. Although he fell two outs shy of recording his first quality start of the season, the 26-year-old righty pitched well enough to get the win and will carry some positive momentum into the All-Star break despite owning an unsightly 7.55 ERA for the season.

The Athletics recalled Serven from Triple-A Las Vegas on Saturday.

Serven will return to the majors as the roster replacement for Nick Kurtz, who landed on the injured list Saturday with a sprained thumb. With Shea Langeliers and Jonah Heim both already on the active roster, Serven will likely see limited time behind the plate.
