From the cards website:
On the other hand, Breyvic Valera is coming from a not so flattering spring. As a second baseman, he slashed .160/.250/.160 over 25 at-bats, coming in second to last among position players on the Cardinals with at least 15 at-bats. He is another player that the Cardinals found and have spent coming up on eight years now developing him into a major league level player.
While he has performed well in the minors and has the utility to play short and outfield, there is one caveat.
Despite slashing an impressive .323/.386/.443 over the last two seasons at Triple A Memphis following a steady climb up the minor league totem pole, Valera has still not developed the kind of pop or bat speed expected from a major league hitters. He only has eight homers and 72 RBI’s over those two seasons after tallying just three homers in six seasons and 770 at-bats in double-A.
He wasn’t able to make it up with speed at the triple-A level either, posting just 19 stolen bases in triple-A on 34 attempts (55.9%). The main thing that Valera provides right now is contact, and unlike Lucas, Valera struggled both in spring and in his brief stint in the majors in 2017. He slashed just .100/.182/.100 over 11 plate appearances in the majors, which doesn’t provide optimism when paired with his poor 2018 spring performance.
That being said, Valera is only 25, and his numbers in triple-A certainly don’t indicate that he is a lost cause. However, it does seem far more likely that the Cardinals would be inclined to allow Valera to walk than they would Lucas"
Looked at his numbers, dude makes contact, rarely strikes out. he was on the cards 40 man roster. so he could be used in case of injuries to our bench
