The Rays officially set their Opening Day roster on Thursday by placing first baseman Ji-Man Choi and outfielder Brett Phillips on the 10-day injured list.

Both moves were expected, as Choi (right knee surgery) and Phillips (strained left hamstring) battled injuries during the final weeks of Spring Training. The Rays had 28 players on their spring roster at the end of camp, so placing those two on the 10-day IL left them with 26 to start the season.

There were no major surprises among the group, which came into focus when the Rays optioned pitchers Josh Fleming, Trevor Richards and Chris Mazza to Minor League camp on Sunday. They are carrying 14 pitchers and 12 position players, with an emphasis on short-inning relievers instead of multi-inning arms due to an early schedule with two off-days during their first road trip.

The composition of the defending American League champions’ roster is bound to change often throughout the season, especially with a stretch of 30 games in 31 days set to begin when the Rays head home to Tropicana Field on April 9 to begin their first homestand.

Here is a look at Tampa Bay’s final Opening Day roster.

Catcher (2): Mike Zunino, Francisco Mejía
This one was pretty clear from the jump, especially with non-roster catcher Kevan Smith sidelined by a back injury during Spring Training. Smith is on the mend, and Joseph Odom joined the team’s taxi squad for the first road trip to provide additional depth. Manager Kevin Cash hasn’t laid out a playing time plan for Zunino and Mejía, but he has said that both will play a lot.

Infielders (6): Willy Adames, Mike Brosseau, Yandy Díaz, Brandon Lowe, Yoshi Tsutsugo, Joey Wendle
Even with Choi injured and 12 hitters on the roster, the Rays have quite a bit of depth here. Tsutsugo and Díaz will share time at first base, and the coaching staff was pleased with the work both did this spring. Díaz looks healthy and fit, and Tsutsugo handled the shift to first base better than many might have expected. Díaz and Tsutsugo can also play third base, and Tsutsugo could still bounce out to left field if necessary.

Lowe will start at second base, though he’s capable of moving over to third and out to the outfield. Adames is the everyday shortstop. Wendle provides strong defense anywhere in the infield, and it’s reasonable to think he’ll get a lot of playing time early on -- potentially at third base -- given how many right-handed pitchers the Rays will face. Brosseau is the quintessential utility man, capable of playing anywhere and mashing off the bench, especially against left-handed pitchers.

Outfielders (4): Randy Arozarena, Kevin Kiermaier, Manuel Margot, Austin Meadows
No surprises here. Meadows looked healthy in Spring Training, which is the most important thing for him. Margot had an outstanding spring, and he’s clearly more comfortable in his second year with the team after a trying year off the field. Kiermaier missed a few days near the end of camp to welcome his second son, Krew Jax, but he appeared to be ready at the plate after adopting a less-is-more approach by necessity last October. Few players will be watched as closely this season as Arozarena, the postseason hero who will bounce between left and right field.

Starting pitchers (5): Tyler Glasnow, Ryan Yarbrough, Rich Hill, Chris Archer, Michael Wacha
Are they officially all starters? Maybe, maybe not. In Miami, the Rays will start Glasnow, Yarbrough and Hill, with Archer set to pitch in relief of Hill in Saturday’s series finale. Wacha will take the mound in some significant role Monday in Boston, although it’s possible he will pitch after an opener the way he did in the Rays’ Spring Training finale.

The Rays will need depth here, and they have as much as any organization in baseball. Among those waiting at the alternate training site, if needed: Fleming, Richards, Mazza, Shane McClanahan, Luis Patiño, Joe Ryan and Brent Honeywell Jr.

Relief pitchers (9): Diego Castillo, Pete Fairbanks, Collin McHugh, Chaz Roe, Cody Reed, Ryan Thompson, Andrew Kittredge, Ryan Sherriff, Jeffrey Springs
This group was dealt a tough blow when righty Nick Anderson, their highest-leverage reliever, went down with an elbow injury that will likely keep him out until August at the earliest. But Tampa Bay is confident in its wide array of options here, starting with Castillo and Fairbanks in the late innings.

Roe and Kittredge will get big outs, especially against right-handed hitters, and Thompson presents a unique challenge to righties with his sidearm delivery. The Rays were thrilled with how good Reed looked this spring, and it wouldn’t be a surprise if he works his way into the mix as a late-inning lefty or potentially an opener in front of their right-handed starters. Sherriff will get grounders and weak contact from the left side, and Springs is an intriguing addition with legitimate swing-and-miss stuff.

McHugh is the group’s wild card, capable of pitching in just about any role given his past history as a starter and reliever. Need three or four innings in the middle of a game? McHugh can do it. Need one out against a righty? He’s got that in him, too.

10-day IL (2): Choi, Phillips

60-day IL (5): Anderson, Jalen Beeks, Yonny Chirinos, Oliver Drake, Colin Poche

Taxi squad (5): Taylor Walls, Kevin Padlo, David Hess, Mazza, Odom
