No more Spring Training speculation: The real games have begun, and the analysis is real. Most believed the Indians were the team to beat in the American League Central, but is that still the case? The Twins certainly look like they'll have something to say about it. Of course, it's far too early to say for certain, but there are things we've learned a week into the season -- and things we still don't know. Let's take a look.

Indians

One thing we've learned: The Indians' offense has gotten off to a slow start through the first few games of the season, shining an even brighter light on the holes that Francisco Lindor (right calf strain and left ankle sprain) and Jason Kipnis (right calf strain) have left. But no matter how cold the bats have been early, the starting rotation has been quite opposite -- aside from ace Corey Kluber's clunker on Wednesday -- proving just how dominant it could be this season.

One thing we still don't know: A big question mark still surrounds Lindor. The Indians have yet to release a firm timetable for his return, but the All-Star shortstop is hoping to come back at the end of April. He is expected to start light baseball activities over the next week, and he will be re-evaluated to determine what his next step will be. The Tribe needs his bat in the leadoff spot in the lineup, as temporary fill-ins Eric Stamets and Max Moroff have had a slow offensive start this season.

One number: 94.8 mph -- the average velocity of Mike Clevinger's four-seamer in his first start on Monday. Clevinger worked all offseason to increase the velocity of his fastball, and it showed in Monday's home opener. In the small sample size, he jumped 1.2 mph from his average last season, which he said was a tick down from what he averaged during the spring due to cold weather.

Royals

One thing we've learned: The top of the order from one through four figures to be productive. Whit Merrifield, Adalberto Mondesi, Alex Gordon and Jorge Soler have already combined for 18 runs scored and 18 RBIs through five games. Gordon has just three hits but has managed to score a team-high seven runs because he has been hit by pitches three times and walked four times. The Royals expect that part of the order to carry them.

One thing we still don't know: The Royals made it a mission to improve their bullpen, signing Jake Diekman and Brad Boxberger, re-signing Wily Peralta and converting Ian Kennedy from the rotation. Early results are mixed, as the bullpen has a 7.27 ERA through five games, 14th in the league. But Kennedy earned his first career save Saturday, and Kyle Zimmer made his MLB debut with a scoreless inning Sunday and could be a weapon.

One number: 0 -- the number of errors through the first five games for the Royals, who are preaching speed and defense in 2019.

Tigers

One thing we've learned: The Tigers can pitch, especially the starters. Jordan Zimmermann and Matt Moore both delivered seven scoreless innings in their first outings, while Matthew Boyd and Spencer Turnbull were one bad inning away from quality starts with 28 strikeouts over 16 1/3 innings combined. All that occurred in the warm confines of Rogers Centre, so it wasn’t the weather cooling the Blue Jays' bats.

One thing we still don't know: Is there a run producer who will emerge in the cleanup spot behind Nicholas Castellanos and Miguel Cabrera? Jeimer Candelario and Niko Goodrum both struggled in the role, leaving manager Ron Gardenhire with a mix of young hitters in the middle of his batting order. Unless somebody steps up, Gardenhire might have to rethink his strategy of batting Castellanos and Cabrera second and third, respectively.

One number: 17 -- the number of times Castellanos and Cabrera were on base without scoring over Detroit's first seven games.

Twins

One thing we've learned: Much of the Twins' rotation stability this season will depend on two relative unknowns -- Michael Pineda and Martin Perez -- and early returns from both starters have been promising. Pineda threw four efficient scoreless innings in his return from Tommy John surgery and a torn meniscus, while Perez showcased his newfound velocity, hitting 97 mph in an extended relief appearance. Successful seasons from that pair will go a long way in stabilizing the Twins' rotation.

One thing we still don't know: What can Miguel Sanó add to this lineup? The Twins don't expect to have their slugging third baseman back in the Major Leagues until May as he recovers from a laceration to his right Achilles area that put a halt to his buildup for the season. Nelson Cruz, Jorge Polanco, C.J. Cron and Byron Buxton are off to fast starts at the plate, but a consistent Sano would make an already deep Twins lineup more formidable.

One number: 21 -- the number of strikeouts by Jose Berrios and Jake Odorizzi in the Twins' first two games. Berrios (10) and Odorizzi (11) became only the second pair of teammates in MLB history to record double-digit strikeouts in each of the first two games of the season -- following Randy Johnson and Curt Schilling for the 2001 D-backs.

White Sox

One thing we've learned: Yoán Moncada is putting into play what he worked on during the offseason. After striking out 217 times and posting a .714 OPS during his first full campaign in 2018, Moncada put in extra time with manager Rick Renteria and hitting coach Todd Steverson to refine his approach. He showed a more aggressive approach earlier in the count and more success with two strikes. The former top-ranked prospect had five extra-base hits among his first nine and looked comfortable defensively at third base.

One thing we still don't know: The White Sox bullpen has the potential to be the AL Central's best with a strong high-leverage, late-inning quartet of closer Alex Colomé, Kelvin Herrera, Jace Fry and Nate Jones. But the group struggled a bit as a whole over the first five games, albeit a very small sample size, as Renteria looks for the right combination. The White Sox need strong seasons from Jones and Fry or someone else to step up into those roles.

One number: 0 -- the number of extra-base hits for Eloy Jiménez, the No. 3 overall prospect per MLB Pipeline, in his first five games and 20 at-bats. Jimenez absolutely will hit and will hit for power. It’s just about adjustments for the talented rookie.
