It was one of his most consistent season. Too bad it was not very good offensively. However, he did have clear good months and clear bad ones, once again.

Yes, he seems to have 1 good/great month per season, but he usually has 1-2 good to decent ones mixed in as well;
2017: 1.009 in June, but also .808 and .770. (That's half the months over .770)
2016: 1.175 in May, but also .839, .807, .805 and .731 (hardly a one good month season, as 4 months were over .805!)
2015: He only played more than 6 games in 2 months- 1.163 and .739 (both not bad to great)
