We've moved on from the day of aces to the day of question marks. One of those question marks is Mat Latos of the Miami Marlins, acquired from the Cincinnati Reds in the offseason to provide a veteran workhorse for the rotation.

Here's how his first inning of 2015 transpired:

Walk, stolen base.

Lineout to left field.

RBI single to left.

RBI double to deep left-center.

RBI double to right-center.

Walk.

RBI double off the left-center scoreboard.

Single up the middle against drawn-in infield.

Sacrifice bunt.

Line drive single.

That was it. Thirty-eight pitches, few of them effective. All the hits except one were hit hard. You really felt bad for Latos, who had nothing from the first pitch and was left in to take the pounding. He become the first starter since Paul Byrd of the Phillies in 2000 to fail to get three outs in one of a team's first two games of the season.

It's certainly not a good sign for the Marlins. Latos was an underrated pitcher with the Reds, but had surgery after the 2013 season to remove bone chips from his elbow, then missed time last season after tearing a meniscus in his knee and missed most of September with a bone bruise in his elbow. Overall, his fastball velocity was down 2 mph and his strikeout rate plummeted, in part because of a decline in his swing-and-miss rate. It adds to a pitcher with diminished stuff who looked like a health risk for 2015.

Instead, the Marlins bet on him bouncing back to the guy who had four straight seasons with 30-plus starts. But the fastball velocity was still down Tuesday night. He threw one pitch at 93 mph and a couple at 92, but was sitting 90-91. His 38th pitch was an 89 mph four-seam fastball. It's only one start, so you don't want to overreact but he also had a similar eight-run outing in one spring training start. The Marlins are also relying on Dan Haren, another veteran with diminishing stuff. It's a risky pair of starters for a team with playoff aspirations.
