Dubon isn't in the lineup for Saturday's game against the Nationals.

Dubon will get a chance to clear his head Saturday after posting just a .513 OPS in 15 games since the All-Star break. His absence will allow Mike Yastrzemski to start in left field while Dominic Smith serves as Atlanta's designated hitter.

The Pirates recalled Mattson from Triple-A Indianapolis on Saturday, Colin Beazley of the Pittsburgh Post-Gazette reports.

Mattson has given up four runs across his last two big-league appearances, but the Pirates will bring him back into their bullpen as the replacement for Antwone Kelly. Sporting a 4.93 ERA and 1.56 WHIP through 34.2 innings in the majors, Mattson will likely be limited to low-leverage work.

The Pirates optioned Kelly to Triple-A Indianapolis on Saturday, Colin Beazley of the Pittsburgh Post-Gazette reports.

Kelly pitched three shutout innings during Friday's loss to the Reds, but he'll now be pushed off the big-league roster by Isaac Mattson in an effort to keep Pittsburgh's bullpen well-rested. Now with a 6.14 MLB ERA through 7.1 frames, Kelly could still return to the majors later in the year to supply the Pirates with length out of the pen.

The Pirates reinstated Flores (concussion) from the injured list Saturday, Colin Beazley of the Pittsburgh Post-Gazette reports.

After suffering a concussion last weekend, Flores is now fully recovered and will claim the roster spot vacated by Ryan O'Hearn (quad), who landed on the 10-day injured list Saturday. Flores has gone 4-for-15 with a homer, two RBI and two runs scored in the majors this year and will provide depth at catcher and first base.

The Pirates placed O'Hearn on the 10-day injured list Saturday with a left quad strain, Colin Beazley of the Pittsburgh Post-Gazette reports.

O'Hearn had to be helped off the field Friday after tweaking his quad while running to first base, and he's expected to remain on the shelf for roughly 6-to-8 weeks after being diagnosed with a strain. His initial timeline leaves room for him to return during the final weeks of the regular season, but the Pirates could elect to keep him out for the rest of the year depending on where they sit in the race for a postseason berth. Until then, Jacob Gonzalez figures to see more time at first base, while Rafael Flores (concussion) will come off the IL to fill the open roster spot.

The Marlins optioned Pauley to Triple-A Jacksonville on Saturday, Christina De Nicola of MLB.com reports.

Pauley appeared in four games after being recalled July 19, during which he went 3-for-9 with an RBI and two strikeouts. He'll now return to the minor leagues in order to make room on the active roster for Owen Caissie (calf), who returned from the injured list Saturday. With a .529 OPS through 106 MLB plate appearances this year, Pauley is unlikely to be a significant contributor for the Marlins if he makes it back to the big leagues.

The Marlins reinstated Caissie (calf) from the injured list Saturday, Christina De Nicola of MLB.com reports.

Caissie played three games after beginning a rehab assignment at Triple-A Jacksonville on Tuesday, going 3-for-7 with two homers and an additional RBI and run scored. He'll now return to the active roster for the first time since July 9, but he'll miss out on the starting nine Saturday with left-hander Zac Thornton toeing the slab for the Mets. Graham Pauley was optioned to Jacksonville in a corresponding move.

Berroa cleared waivers Saturday and was sent outright to Triple-A Lehigh Valley.

Berroa lost his spot on the Phillies' 40-man roster last weekend, but he'll stay put at Lehigh Valley after passing through waivers. The 27-year-old owns a .762 OPS through 262 plate appearances in the minors this season.

The Yankees traded Doval to the Pirates on Saturday in exchange for minor-leaguers Omar Alfonzo and Luis Cruz, Jeff Passan of ESPN.com reports.

Doval owns a 4.54 ERA and 1.41 WHIP through 39.2 innings this season and had been losing out on high-leverage work with the Yankees, recording just one hold and no saves in his last 23 appearances. He might not immediately be in the mix for saves upon joining the Pirates, but the 29-year-old's experience as a closer could allow him to climb up the leverage ladder quickly if his performance improves.

Polanco isn't in the lineup for Saturday's game against Miami, Anthony DiComo of MLB.com reports.

Polanco will begin Saturday's contest in the dugout after failing to record a hit in 23 at-bats across his last seven games. Bo Bichette will serve as the Mets' designated hitter, opening up third base for Brett Baty.
