Observations from Mets’ spring training on Monday:
Nice ABS
Carlos Mendoza said the team would be aggressive this spring when it came to using the new automated ball-strike challenge system.
They were aggressive again Monday, as Clay Holmes’ outing ended when Hayden Senger challenged a ball call with Toronto’s Addison Barger at the plate.

The pitch proved to be a strike, which resulted in a strikeout for Holmes.
Spiked
Vidal Bruján was forced from the game when he was spiked on his left thumb as he dove headfirst into second on a stolen-base attempt in the top of the sixth inning.
Caught my eye
Jared Young is among those getting time at first base this spring, and he made a nice backhanded play on an Andrés Giménez grounder.
Mark Vientos, who started at first Sunday and could split time with Brett Baty as Jorge Polanco’s backup, was the DH.
Tuesday’s schedule
The Mets will start right-hander Jack Wenninger when they host the Astros at 1:10 p.m. at Clover Park.
Wenninger was the team’s 11th-ranked prospect last year, according to MLB Pipeline.
