This slip joins two games that have no common premise. Each was judged on its own, and each rests on how that particular matchup is likely to unfold late on.
Guinea v Kenya (football): both teams to score. Guinea are the stronger side on paper, and the market prices them that way. The part we think is underpriced is what happens after the hour mark. When Guinea chase or try to push a lead at home, their shape opens up and they have conceded in most of their recent home games. Kenya do not need much of the ball to hurt a team that is stretched. Their goals come late, through Olunga, Ogam and players from the bench running into space behind. So the question is not only whether Guinea score. It is whether Guinea's way of attacking creates the chances Kenya need. We think it does. What could go wrong: if Guinea score early and then sit deeper and manage the game instead of pressing, the late space may never appear. National-team line-ups are also not announced before our deadline, so the forwards Kenya bring could differ from what we expect.
Chiba Lotte v Nippon-Ham (baseball): Nippon-Ham on the run line. This is not a simple case of the better team winning. Lotte are starting a converted reliever who is unlikely to go deep, and their bullpen has been worked hard recently. That puts innings from tired arms against a Nippon-Ham order that is at full strength. At the other end, Kitayama faces a Lotte offence that has struggled to score. A run-line bet needs Nippon-Ham to win by more than a single run. That depends on the middle and late innings, where Lotte's pitching is weakest. What could go wrong: a close, low-scoring game where Nippon-Ham win by only one run would lose this leg. If rain shortens the game, run-line settlement can be voided.
Other notes The two legs are independent, so one wrong reading does not drag the other down through a shared assumption. However, both have to come in for the slip to win. That is why the stake is moderate.
