Yordan Alvarez is putting together an MVP-caliber season at the plate, and his success should continue on Sunday Night Baseball.
He headlines three bats I'm backing with my Astros vs. Padres props and MLB picks for Aug. 9.

Astros vs Padres player prop picks
Yordan Alvarez Over 1.5 0.5 RBIs (+120)
Randy Vasquez ranks in the third percentile in both xBA and xERA. He allows a ton of quality contact and bleed hits, which will lead to plenty of traffic on the bases.
This is a great spot for the Houston Astros as a whole to string together hits and keep the train moving. That won't afford opportunities to pitch around Yordan Alvarez.
He ranks third in the majors in RBIs and is a 100th percentile hitter in xwOBA, xSLG, and xBA.
Play to +110.
Jeremy Pena Over 0.5 singles (-155)
Jeremy Pena picked up at least one single in 60% of his games this season, and this is a prime spot to add to that output.
Vasquez owns a poor 1.41 WHIP despite strong walk suppression numbers because of his inability to limit hits. That sets up well for Pena, who owns an impressive .312 batting average against right-handed pitching this season.
Pena has hit .300 or better against each of Vasquez' three most-used pitches vs. righties, giving him few options to attack and get Pena out.
I'd bet Pena up to -170.
Fernando Tatis Jr. Over 0.5 singles (-110)
Cristian Javier has given up hits in bulk, allowing 10.28 per nine innings. He has struggled against righties in particular, allowing a .305 average.
That's good news for Fernando Tatis Jr., who has singled in 55% of his games this season and 65% when isolating home dates.
While Tatis Jr. does have some barrel ability in his bat, he has struggled hitting for power against fastballs. His ISO sits at .073 facing four-seamers, and that is by far Javier's most-used pitch.
I like Tatis Jr. to pick up a single, and would bet this to -133.
