Alonso has struggled against southpaws all season, hitting just .183/.266/.423 in 71 at-bats, so get the day off with lefty Cole Hamels toeing the rubber for the Rangers. In his place, Danny Valencia is starting at first base and batting sixth.
Miguel Cabrera was the DH in this one, which allowed Navarro to snag a start at first base. The 31-year-old journeyman is simply a depth option at this point, but he could garner a few more starts the rest of the way as the Tigers have nothing to play for.
The left-handed Jon Lester is headed to the hill for the Cubs, so Duda will take a seat Thursday night. Cesar Puello will serve as the Rays' DH while Duda gets the night off.
Even with the three hits, Cabrera is still hitting just .249. The 34-year-old has only batted below .300 in a season once in his career, and that was in 2008 when he posted a .292 mark. Cabrera has dealt with a variety of injuries this year, so he could bounce back in 2018 with better health. However, at this stage in his career, it wouldn't be too surprising if Cabrera's overall production started to decline.
Alonso is just 13-for-70 (.186) against left-handers this season, so he will be held out Tuesday with the Mariners taking on southpaw Martin Perez. Danny Valencia will get the start at first base in Alonso's place.
Travis has just one at-bat since his last start Sept. 12, so manager John Farrell will include him in the lineup a couple days in a row in an effort to keep him sharp. Travis will serve as the designated hitter Tuesday night and hit seventh against Orioles starter Kevin Gausman.
For the first time eight-year career, Alvarez reached base five times in a single game. He's hitting .333/.429/.667 through 14 plate appearances since being recalled earlier this month. The once prominent MLB slugger has only two starts in his eight games thus far, but Alvarez is a decent value option in daily formats when the veteran is in the lineup.
The surging slugger now has a homer in four consecutive games and 14 over his past 20 contests. Olson boasts a monster 1.132 OPS with 33 RBI and 25 runs through just 36 games since returning to the big club Aug. 8. While the 23-year-old first baseman is almost certainly overachieving right now, his heater could easily extend through the end of the regular season.
After missing Sunday's outing due to a tight back, Cabrera is in the lineup Monday. He'll slot in at the DH spot and hit third against Jharel Cotton and the A's. Over his last seven games, Cabrera has gone just 5-for-24 (.208) and struck out seven times.
Olson's torrid September evokes memories of the type of effort that another rookie, the Dodgers' Cody Bellinger, put together earlier this season, as he now has 10 round trippers and 17 RBI over just 16 games. In addition to going deep in all three contests versus the Phillies, Olson has six homers overall in the last eight games. He's mostly gotten base via single otherwise, as the 23-year-old counts a pair of two-baggers as his only other extra-base hits for the month.
