Machado went 1-for-3 with a two-run home run, a walk and an additional run scored in Tuesday's 9-7 win over the Nationals.

Advice: Machado has gone 14-for-38 (.368) over his last 10 contests, adding two homers and eight RBI in that span. The third baseman opened the scoring when he took MacKenzie Gore deep in the first inning Tuesday. Machado is still playing catch-up after a slow start to the campaign, but he's up to a .260/.314/.389 slash line with eight homers, 40 RBI, 34 runs scored and five stolen bases through 76 contests. His .703 OPS is the highest it's been since May 5. Rotowire.com 17 minutes ago

Luis Castillo allowed four runs on five hits in 5 1/3 innings in a loss to the Rays on Tuesday.

Advice: The Mariners ace struck out four and walked four on the day. He wasn’t sharp, with just a 44 percent zone rate on the day, but he had kept it together until the sixth inning. With the game tied at two, Castillo got one quick out but walked the next two hitters and was chased from the game. Michael Baumann then allowed a triple and a home run to bring in both inherited runners. Castillo had nine whiffs on 44 swings for a 20 percent whiff rate and 29 percent CSW on the day. We can probably chalk this up to a poor start, but it’s his second straight one so we’d like to see him right the ship next time out. The only problem is that the start comes against the Orioles.

Polanco (hamstring), reinstated from the injured list earlier in the day, went 0-for-4 with three strikeouts in a loss to the Rays on Monday.

Advice: Polanco finished up his rehab assignment with Triple-A Tacoma by belting three home runs and compiling six RBI over his final two games, but that prodigious bat was nowhere to be found in his return to the big leagues Monday. The veteran disappointingly reverted to the struggles that have defined most of his season, and following Monday's trio of punchouts, Polanco now sports a career-worst 31.9 percent strikeout rate.

Munoz was charged with a blown save Monday against Tampa Bay, allowing one hit and one walk with one strikeout in one-third of an inning.

Advice: Munoz entered the game in the bottom of the eighth inning with two outs and runners on second and third. He walked Jose Caballero before allowing a two-run single to Yandy Diaz, giving the Rays a 4-3 lead. While Munoz blew the save, it is encouraging that he was called upon for the high-leverage situation over fellow closer Ryne Stanek, who pitched a scoreless seventh inning. The Mariners closer situation should still be considered a committee moving forward, with Munoz offering the most upside. Despite blowing the save, the 25-year-old has been dominant this season, compiling a 1.41 ERA, a 1.00 WHIP and a 43:11 K:BB over 32 innings, converting 13-of-15 save opportunities with six holds.

Snell (groin) will throw a bullpen session Tuesday and make another rehab start for Triple-A Sacramento on Friday, Shayna Rubin of the San Francisco Chronicle reports.

Advice: Snell showed signs of rust during his first rehab appearance with Sacramento on Sunday, and as expected, he'll make at least one more start in the minors before the club considers activating him from the 15-day injured list. The southpaw fired 51 pitches Sunday and will continue to build toward a full workload in his upcoming appearance as he makes his way back from a left groin strain. Rotowire.com Yesterday, 4:10 pm
