Mariners at Rangers picks and predictions

Prediction

Rangers 3, Mariners 2

Moneyline

A good pitching match-up and 2 evenly-matched teams overall. Can’t split ’em: PASS.

Run line/Against the spread

Same gray area as above but surrounded by more juice. AVOID.

Over/Under

Both clubs have some offensive numbers not fully supported by analytic measures, and that opens up their combined efforts to an Under lean.

The concept of batting average on balls in play figures prominently in how both offenses can be figures as being too far over their skis. The MLB average BABIP is .297, and it’s a “sticky” number with gravity: when splits are significantly above or below that .297, we can project some movement back the other way.

Key Seattle BABIPs: .306 in road games, .316 with runners in scoring position, .352 last month (when perhaps many bettors started to overrate what has mostly been an average offense).

Key Texas BABIPs: .314 overall, .325 with RISP, .330 in high-leverage situations.

In a game with two solid starting pitchers … with back ends of bullpens fully available … and with a Texas bullpen being underrated by a significant margin, BACK THE UNDER 8.5 (-110).
