Retro, set, go: Throwback uniforms return

In addition to today's packed slate of 16 Major League games, it's Turn Back the Clock day, MLB's new annual tradition featuring eight teams sporting iconic throwback jerseys.

The Red Sox and Giants will be among the clubs wearing retro uniforms when they meet tonight in an Interleague matchup at Fenway Park. Recently acquired starter Drew Pomeranz is set to make his Red Sox debut, and Matt Cain returns to the mound for the Giants after missing more than a month to the disabled list.

Elsewhere today, the Mets and Cubs meet in a rubber game at Wrigley Field, Justin Verlander starts for the Tigers, Felix Hernandez gets the ball for the Mariners and Marcus Stroman toes the rubber for the Blue Jays. There's an extra game on the docket because the Padres and Cardinals will play a doubleheader in St. Louis.

And the best place to catch all the action is on MLB.TV.

Here's what to watch for today in the Majors (all times ET):

Pomeranz debuts for Sox: SF@BOS, 7:10 p.m.
Red Sox fans get their first look at Pomeranz (8-7, 2.47 ERA), who was pried from the Padres on Thursday. It's the fifth organization in six years for the left-hander, and he seems eager to begin a new chapter in Boston. The Sox lead the American League Wild Card race and have won seven of their last eight games.

"Yeah, it's pretty exciting coming here, being on a team that all they want to do is win out there, and I'm excited to get out there on the mound and get that first start under the belt and keep going," said Pomeranz, who was 0-2 with a 2.60 ERA in three appearances against the Giants this year as a member of the Padres.

Meanwhile, Cain (1-5, 5.34) makes his first start with the Giants since June 13. He's been limited to 11 starts this season because of a right hamstring strain that has twice sent him to the disabled list. The first-place Giants are looking for Cain to help them end a four-game losing skid.

Stat that matters: Red Sox slugger David Ortiz has four home runs in his last five games at Fenway Park, including a three-run shot on Tuesday.

DeSclafani looks to stay unbeaten: ATL@CIN, 12:35 p.m.
The Braves and Reds wrap up a three-game series and get today's action started in the first Turn Back the Clock game. Anthony DeSclafani (4-0, 2.55) starts for the Reds as he tries to remain unbeaten in his eighth outing of the season. He's been on a tear of late, going 4-0 with a 2.67 ERA over his last five outings. The Braves, who won Tuesday's game in 11 innings, will counter with Lucas Harrell (1-1, 3.63).

Stat that matters: DeSclafani's stretch of five quality starts is the longest such streak by a Reds pitcher this season.

Contenders meet for rubber game: NYM@CHC, 2:20 p.m.
It seems fitting that 19-year veteran Bartolo Colon (8-4, 3.11) gets the ball for the Mets in their Turn Back the Clock game against the Cubs. Colon, 43, is the oldest player in the big leagues this year. The Mets won Tuesday's game and have beaten the Cubs in nine of their last 10 meetings (including the 2015 postseason). Colon last faced the Cubs on July 2, earning the win with six innings of two-run ball.

The first-place Cubs will counter with Kyle Hendricks (8-6, 2.41). He's been great at Wrigley Field this year, going 6-1 with a 1.50 ERA. Hendricks ranks third in baseball in overall ERA, and his ERA at home ranks second in MLB. He's beaten the Mets in each of his two career regular-season starts against them.

Stat that matters: The Cubs' Ben Zobrist is 9-for-17 (.529) lifetime against Colon, with four homers and one triple.

Santiago looks to continue scoreless streak: TEX@LAA, 10:05 p.m.
In the final Turn Back the Clock game of the day, the first-place Rangers play the division rival Angels for the final time before the middle of September.

Lefty Martin Perez (7-6, 4.05) gets the ball for the Rangers in his 20th start of the season, which will match his career high. Perez is looking for better results after giving up 17 runs (12 earned) in 9 2/3 innings combined over his last two outings. Before this rough stretch, Perez was 6-0 with a 3.28 ERA in his previous eight starts.

Hector Santiago (7-4, 4.27), another southpaw, starts for the Angels. Santiago has not allowed an earned run over his last three starts, totaling 20 innings. He's won his last four decisions dating back to June 15. In three starts against the Rangers this year, Santiago is 0-2 with a 7.07 ERA.

Stat that matters: Angels slugger Albert Pujols has 578 homers in his career, including 16 in 76 games against the Rangers, and is five shy of tying Mark McGwire (583) for 10th on the all-time list.
