Yelich starting to get hot after his horrendous start. His OBP and slugging percentages are actually decent (not superstar level, but decent). His batting average looks like a pitcher's.
He's 7 for 47 with 9 walks in 12 games. His 7 hits include 1 single, 1 double, 1 triple, and 4 home runs.
If you extrapolate his current stats out to a whole year they are the following:
87 hits, .149 average, 50 HRs, 112 RBIs, 250 strikeouts, 112 walks
Last year he had 75 singles in 130 games. This year 1 in 12 games. Basically, his whole statistical problem right now comes down to he's not getting any singles or enough doubles. He either hits the ball hard or strikes out right now (20 Ks in 47 ABs).
