New York Mets rookie right-hander Dedniel Nunez (forearm) started playing catch at 60 feet on Saturday, according to manager Carlos Mendoza, and is no longer feeling soreness in his right forearm. Nunez had emerged as a key piece of the team's bullpen this year before suffering a right-pronator strain, posting a 2.43 ERA and 0.93 WHIP over 33 1/3 innings in relief. The 28-year-old reliever landed on the 15-day injured list on July 26 but could return to the Mets' bullpen sooner than later now that he's resumed throwing without pain. However, it's unlikely that he'll come off the IL when he's eligible this Thursday. The Dominican hurler picked up the first save of his career earlier this year and has struck out 45 hitters and walked only eight in his first big-league season.

New York Mets right-hander Sean Reid-Foley (shoulder) walked three of the five batters he faced in his minor-league rehab outing for Double-A Binghamton on Sunday, throwing 25 pitches while recording a strikeout. Reid-Foley was set to check in with the team's medical staff in New York on Monday before being dispatched on another rehab outing later in the week. Manager Carlos Mendoza said that Reid-Foley's readiness to return to the big-league club will partly depend on his performance with Binghamton. "We want to see how the ball is coming out of his hand and how he's going to bounce back," Mendoza said. "We're going to need him when he gets here to go back-to-back [days] and one-plus [innings]." The 28-year-old had an impressive 1.66 ERA and 1.25 WHIP with 25 K's but also 14 walks in 21 2/3 innings of relief for the Mets before suffering a right-shoulder impingement.

New York Mets right-hander Reed Garrett (elbow) allowed three earned runs in just one-third of an inning for Double-A Binghamton on Sunday, but manager Carlos Mendoza said he came through the outing feeling physically strong. Garrett returned to New York on Monday to check in with the team's medical staff and will be sent back out for another minor-league rehab outing at an affiliate to be determined later this week. The 31-year-old has been out since the middle of July with right-elbow inflammation but is back to pitching in games and could return from the 15-day injured list sooner than later. Before his injury, Garrett was 7-3 with a 3.64 ERA (3.74 FIP), a 1.43 WHIP, his first four career saves, a career-high 63 strikeouts and 22 walks in 42 innings out of the Mets' bullpen. He could be a key relief arm for New York once he returns as the Mets look to secure a wild-card spot in the National League.

New York Mets third baseman Mark Vientos (ankle) fouled a ball off his right ankle in the top of the fourth inning in Sunday's series finale in Anaheim against the Los Angeles Angels, which is why he did not play on Monday against the St. Louis Cardinals. Manager Carlos Mendoza said Vientos was scheduled to go through his regular pregame routine in St. Louis but that he was being held out of the starting lineup. "Kind of [swelled] up after the game, but he's better today," Mendoza said. "He's a player for us, but I just wanted to give him a day." The Mets basically just wanted to give the 24-year-old a day off on Monday, so there's a good chance he'll be back in action on Tuesday versus the Colorado Rockies at hitter-friendly Coors Field.

Atlanta Braves outfielder Michael Harris II (hamstring) will start a rehab assignment on Tuesday night at Triple-A Gwinnett, the Braves announced. Harris has been on the IL since June 15 with a strained left hamstring. He hit .250 with five homers, 20 RBI, and eight stolen bases this season for the Braves in 67 games before the injury. He will likely need a few games at Gwinnett to ramp up but this is very good news for fantasy managers as well as the Braves. If Harris was cut loose in fantasy leagues, it would be wise to scoop him up for the stretch run.
