McDonald Faces a Tall Task for San Francisco
Trevor McDonald gets the start for San Francisco with a 2-6 record, 4.94 ERA and 1.35 WHIP across 51 innings, allowing 50 hits, 19 walks and four home runs while striking out 45. That inexperienced profile puts extra pressure on the Giants' lineup to keep pace in this series finale.

Gallen's form is difficult to trust, but Arizona has been the better team lately and has already controlled this series.
