The San Diego Padres worked hard over the winter to upgrade their starting rotation, and the moves have paid off already in the 2021 MLB season. Joe Musgrove, Yu Darvish and Blake Snell have combined to post a 3-0 record and 1.70 ERA, while Musgrove also produced the first no-hitter in franchise history. Should you expect Snell to come up with another strong start for the Padres on Tuesday, or is there value in the Pittsburgh Pirates hitting him hard and bringing a large return on the money line?

Top MLB picks for Tuesday, April 13

One of the MLB picks the model loves for Tuesday: The Kansas City Royals pick up the win at +125 on the money line against the Los Angeles Angels. Kansas City was unable to control Los Angeles' offense in Monday's season opener, as Mike Trout homered and Shohei Ohtani went 3-for-5 with three RBIs in the Angels' 10-3 victory. The Royals surrendered 14 hits in the setback but are likely to have a better showing with Danny Duffy on the mound. The 32-year-old left-hander was superb in his season debut at Cleveland, limiting the Indians to only two hits in six scoreless innings.

Duffy settled for a no-decision in that outing, which marked the third time in four starts dating back to last season that he gave up fewer than two runs. Kansas City is hoping Salvador Perez can continue to swing the bat well after his performance on Monday. The 30-year-old catcher went 4-for-4 with an RBI in the series opener after entering the contest just 5-for-27 on the season.
